Review Comment:
   Yes, it's safe in this `main` method for `SetGoalState`. We're exiting immediately after anyway. The only thing my change did was make sure the resource was closed so it shut down any internal thread pools before the process exits. This got rid of a warning after removing the other line. I'm not sure why my IDE didn't see the warning before, but it didn't. It only noticed the unclosed resource after I deleted the other line.
